Application filed March 30, 1914. ,'SerialNo. 828,315; fr i y To allwhom it may concern:

Be it known that I, RICHARD OTERs, a citizen of the United States,residing at Osf sining, in the county of Vestchester',-5Statef of NewYork, have invented certain new and useful Improvements in Lawn-Mowers;and I do hereby declare the following; to be a full, clear, and exactdescription of they.l invention, such as will enable others skilledV inthe art to which itappertains to make and use the same.

y This invention relates to lawn mowers. Y

The object of the invention resides in the provision of a lawn mowerembodying an improved simplified construction, and which will bedurable' and eflicient in use.

With the above and other objects in view the invention consistsin thedetails of construction and in the arrangementandcombination of parts tobe hereinafter more fully described and particularly pointed out in theappended claim. i

In describing the inventionin detail refyerence will be had to theaccompanying drawings wherein likecharacters of reference denotecorresponding parts 1n the several views, and 1n which` Y Figure 1 is aplan View ofa lawn mower constructed in accordance with the invention;Fig. 2, a front viewof the lawn` mower; Fig. 3, a rear view partlybroken away and partly in section; Fig. 4, a side view of the lawnmower; Fig. 5, a section on the line 5 5 of Fig. 4'; Fig. 6, a view ofthe large traction wheel of the lawn mower i looking at the inner sideof said wheel; Fig,

7, asection on the line 7 7 of Fig. 2; Fig. 8, a section on the line 8-8of Fig. 7; Fig. 9, a view of the disk which is fixed on the axle of thelawn mower and looking at the inner side thereof, and Fig. 10,- atransverse section through the handle of the lawn mower. v

Referring to the drawings the improved lawn mower is shown as comprisinga handle- 15 which has adjustably secured thereto bracket arms 16 and17.` Mounted in the free ends of the arms 16 and 17 is an axle 18- uponwhich is rotatably mounted a traction wheel 19 having an inwardlydirected peripheral flange 20 andformed on the inner side ofsaidtraction wheel is an annular rack 21. The axle 18 is provided with an'enlarged central portion 22 in which is r0- tatably mounted a.transverse shaft 23.

Fixed on the axle .1S is a sleeve 24 the Outerv fined substantiallywithin the peripheralv Fixed on the end of the shaft 23 disposedexteriorly of the sleeve 24 is a crank arm 26 for a purpose that willpresently appear.

Fixed on the .end of the shaft 23 confined l within thesleeve 24 is agear 27 which `meshes with a kgear 28 lixed on a shaft 29 rotatablymounted in bearings 30 carried on the'inner side of the disk 25. Alsofixed on the shaft 29 is'a gear 31- which meshes with theV rack 21.ySupported fromthe. disk 25 by means of bracket arms 32 is a guard VVbar33 provided with the usual yguard fin- `endvoffwhich.terminates disk-25con# ,v

gers 34and having a longitudinal `groove 35 in its upper side. The endlof thebar'33 remote from the disk 25 is provided withv an upturnedportion 36 through which is.

transversely engaged'a bolt 37 and rotatably mounted on 'this bolt 'is asmall traction wheel 38 which serves to support the outer end of saidbaras will be obvious. Slidably mounted in the groove 35 is a sickle`bar 39 which is adapted to be reciprocated through the medium of apitman 40 one end of whichl Y is connected to a heel 41 4formed on thesickle bar and the other end to the crankarm 26.

It will vbe noted that the upturned end 36 of the bar 33 is provided onl'its outer sidel with -a groove 42 Vin which is'slidably en-` gaged anextension 43 of the hub of lthe wheel 38. The upturned end 36 isprovided with a plurality of openings 44 in which the bolt 37 is adaptedto be interchangeably eni i lgaged and whereby the .wheel 38 may beadjusted vertically. v

By this construction it will be obvious that as the devicey moves alongthe ground the wheel 19 will be rotated and this rotasoA tion of saidwheels will effect a rotation ofV l ,stepped 9,11 its under Sd Q QlmShoulders;

an annularV rack formed on one of said shoulders, a disk fixed on saidaXle and provided With a peripheral flange forming a bearing for theperipheral flange of the traction Wheel, a shaft rotatably mounted lCopies of this patent may be obtained for portedfrom the axle, a sicklebar mounted for reciprocationonthe guard bar, and a pitman connectingthe sickle bar and said crankarm.
